Caliper INSIZE SUWMIARKA 150 digital, 150 mm measuring range, metal case, zinc-coated, model 1114-150AW

Digital caliper INSIZE SUWMIARKA 150 (model 1114-150AW) is a precision measuring instrument with a 150 mm measuring range and an electronic digital display. The caliper is designed for external, internal and depth measurements and is supplied with a metal protective case with zinc coating for secure storage and transport. It is suitable for workshop use, inspection tasks and general mechanical measurements where compact, accurate digital readout is required.

Advantages

The caliper provides fast, clear numeric readout via an electronic display, reducing reading errors compared with analog scales. Its 150 mm measuring range covers common small-part dimensions while the metal zinc-coated case protects the instrument from impacts and contamination during storage. The device combines external, internal and depth measuring functions in a single compact instrument and offers straightforward operation suitable for routine measurement tasks.

Suitable for

• Workshop measurements of small mechanical parts
• Quality control and inspection of components
• Internal and external diameter checks
• Depth measurements of grooves, holes and slots
• Maintenance and repair tasks requiring quick dimensional checks

Key specifications

• Measuring range: 0–150 mm
• Display type: electronic digital readout
• Measuring functions: external, internal and depth measurement
• Construction material: precision stainless measuring surfaces with hardened jaws (measuring surfaces metal)
• Protective case: metal case with zinc coating for storage and transport
• Resolution: typical 0.01 mm (digital)

How to use

Before measurement, ensure the caliper surfaces are clean and the sliding jaw moves smoothly. Zero the digital display with the jaws closed, then place the instrument on the workpiece according to the required measurement type: close the jaws for external diameters, insert the jaws for internal diameters, or use the depth rod for depth measurements. Read the value directly from the digital display and record as needed. After use, wipe the caliper clean of debris and return it to the protective metal case to avoid damage.

Usage recommendations

Store the caliper in its zinc-coated metal case when not in use, keep measuring surfaces free of oil and dirt, and avoid exposing the instrument to strong impacts or excessive humidity. For accurate results, perform periodic calibration or comparison with a reference gauge and replace the battery promptly if display dimming or unstable readings occur.
